cxp21 rims/spoke lengths

I am having trouble getting spoke lengths for a 650c wheel build
because my database doesn't include mavic cxp21's. I am building a
wheelset w/ ultegra 32 hole hubs, cxp21 650c rims. i am using radial
front, please no lectures, it is a rebuild and i want to keep it same.
i am using 3x both sides rear. If anyone can supply me w/ spoke
lengths, I would appreciate it.
thanx,
andy

Andy,
Go to Sheldon Brown's web site at URL:

You will see how to measure the ERD there. You can then input that ERD data
into the spoke calculator that is also on the site. David Ornee, Western
